    Photo electric effect supports the quantum nature of light because:

    In photoelectric effect,

    Assertion : Photoelectric effect supports the quantum nature of light. Reason : Photoelectric emission is instantaneous.

    Assertion: Photoelectric effect supports the quantum nature of light. Reason : Electric charge of photoelectrons is quantised.

    Assertion : The threshold frequency of photoelectric effect supports the particle nature of light. Reason : If frequency of incident light is less than the threshold frequency, electrons are not emitted from metal surface.
